“…36,37 Our previous results indicated that galloylated A-type PA dimers inhibited 3T3-L1 preadipocyte differentiation by a lipid raft-involved mechanism. 17 In our previous study, we found that MβCD, which is a lipid raft disturbing agent, could block 3T3-L1 preadipocyte differentiation through downregulating signaling such as PPARγ, C/ EBPα, sterol regulatory-element binding proteins (SREBPs), and other related downstream genes, 38 which was highly consistent with that of galloylated B-type PA dimers. Therefore, we hypothesized that the different inhibitory effects of three B-type PA dimers on 3T3-L1 cell differentiation might be due to their different structural disturbing potencies on lipid rafts.…”

“…15 Our previous study demonstrated that the galloylated A-type dimers (A-ECG dimer/A-EGCG dimer) inhibited preadipocyte differentiation stronger than that of the nongalloylated dimers (A-EC dimer/B-EC dimer), indicating that the presence of the galloyl group in the structure of PAs might play a vital role in their differential inhibitory potency on 3T3-L1 preadipocytes. 16,17 Our further studies indicated that galloylated PAs could interfere with the cell membrane structure strongly. 18,19 Considering the lipid rafts, which were enriched in cholesterol (CHOL), sphingolipids and signal proteins, are small and dynamic nanodomains in cell membranes acting as functional platforms for the regulation of cellular processes.…”

“…Another study showed that A-type ECG/EGCG dimers could form the H-bond with more deeply inside lipid oxygen atoms, while the A-type EC dimer preferred surface oxygen atoms. 17 Taken together, the galloyl moiety plays central roles in the interaction between B-type PA dimers and lipid rafts.…”

The effects of three B-type proanthocyanidin (PA) dimers covering procyanidin B2 (B-0g), procyanidin B2 3′-O-gallate (B-1g), and procyanidin B2 3,3′-di-O-gallate (B-2g) on 3T3-L1 preadipocyte differentiation and the underlying mechanisms were investigated. The results showed that digalloylated B-type PA dimers (B-2g) strongly inhibited 3T3-L1 preadipocyte differentiation through disrupting the integrity of the lipid raft structure and inhibiting the expression of peroxisome proliferator-activated receptor gamma (PPARγ) and CCAAT/enhancer-binding protein alpha (C/EBPα) and then downregulating the expression of acetyl-CoA carboxylase (ACC) and fatty acid synthase (FAS) factors, followed by B-1g, while B-0g had little effect. The different inhibitory effects were mainly due to the difference in the B-type PA dimer structure and the ability to interfere with lipid rafts. The greater the galloylation degree of B-type PA dimers, the stronger the ability to disrupt the lipid raft structure and oppose 3T3-L1 preadipocyte differentiation. In addition, galloylated B-type PA dimers had greater molecular hydrophobicity and topological polarity surface area and could penetrate into the lipid rafts to form multiple hydrogen bonds with the rafts by molecular dynamics simulation. These findings highlighted that the strong lipid raft-perturbing potency of galloylated B-type PA dimers was responsible for inhibition of 3T3-L1 preadipocyte differentiation.

“…The facets can be tuned and device performance can be altered significantly by controlling the growth direction and crystallization kinetics. Surfactants and ligands have recently been discovered to have an important role in altering the surface energy of PSCs and achieving anisotropic growth. ,,,− Organic compounds act as additives in perovskite precursor solutions to control the formation of perovskite single crystals, affecting both nucleation and crystal growth processes. In perovskites, additives with a strong interaction with ions can control the pace of growth of distinct facets and, more critically, prevent the creation of point defects.…”

Single crystals of semiconductor materials have been extensively studied in optoelectronic applications because of the absence of grain boundary, lesser defects, and long-range order of crystallinity. Due to their multifaceted character, crystals are very often found to have significant anisotropic properties. These anisotropic properties lead to a considerable variation in their fundamental properties and optoelectronics applications. In the past decade, halide perovskites have emerged as one of the most exciting classes of semiconductors due to their rich photophysical properties leading to applications in solar cells, light-emitting diodes, photodetectors, etc. Especially, perovskite single crystals (PSCs) with an absence of grain boundaries, remarkably longer carrier diffusion lengths, significantly lower trap densities, and longrange order have received wide attention in large-scale device deployment. Interestingly, PSCs also exhibit strong anisotropy-dependent fundamental properties, and correspondingly their device applications are highly tunable. Here, in this feature article, we address a molecular perspective focusing on the structural, optical, and electronic anisotropy in PSCs. In addition, we discuss how anisotropy can affect the performance of PSCs-based devices. Furthermore, we highlight the future directions for implementing a fundamental understanding of the anisotropic response of PSCs to design novel and emergent optoelectronics devices.

Low dialysis and blood incompatibility efficiency are key issues to be addressed for polymeric hemodialysis membranes. To improve the comprehensive performance of hemodialysis membranes, polyethersulfone (PES)/tannic acid (TA) coblended ultrafiltration membranes were prepared and modified with a heparin-like functionalized TA coating. The coblended TA improved the pore structure of the PES ultrafiltration membrane. And it could also undergo π-π conjugation with the heparin-like functionalized TA in the modified solution, resulting in a greater abundance of modified groups loaded on the membrane surface and pores close to the surface. The modified coating further improved the membrane performance. The physicochemical properties, solute filtration, and blood compatibility properties of the membrane were tested. The effect of TA on the pore structure of the membrane and the presence of modified layers were demonstrated by morphological and chemical structure analyses. The final modified membrane had an ultrahigh water flux (1053 L/m 2 Áh), improved dialysis performance (BSA retention >99%, Lysozyme clearance >30% and Urea clearance >90%), and excellent hemocompatibility (The hemolysis rate was 1.31%, and APTT, PT, and TT values were increased by 40.8%, 74.2%, and 85.9%, respectively). This study shows that TA has great potential for improving the pore structure of polymeric membranes.
